If you use an iPhone, iPad, Mac, Apple Watch or Apple TV, listen up. Apple has released a major security update to fix a zero-day vulnerability, which is a security hole that hackers discover and exploit before the company has a chance to fix it. 

Attackers were already using it in targeted attacks. In other words, this was not just a possibility. It was happening.

The flaw, tracked as CVE-2026-20700, affects multiple Apple operating systems. If you have delayed updates lately, this is one you should not ignore.

If you own an Android or Windows PC, this is also a good reminder to check for updates.

APPLE PATCHES TWO ZERO-DAY FLAWS USED IN TARGETED ATTACKS

What is CVE-2026-20700 and why it matters

CVE-2026-20700 is a memory corruption vulnerability affecting:

• iOS 26.3
• iPadOS 26.3
• macOS Tahoe 26.3
• watchOS 26.3
• tvOS 26.3
• visionOS 26.3

In simple terms, this bug could allow an attacker to run arbitrary code on your device. That opens the door to spyware, hidden backdoors or silent takeovers without obvious warning signs. Apple says this vulnerability was used as part of an infection chain combined with two previously patched flaws against devices running older versions of iOS. Those earlier bugs were fixed in December 2025. Devices that skipped those updates remained exposed. This is how many real attacks unfold. Hackers chain vulnerabilities together and quietly move in.

Which devices need updating?

Here is a breakdown of the available updates:

• iOS 26.3 and iPadOS 26.3 for iPhone 11 and later, plus newer iPads
• iOS 18.7.5 and iPadOS 18.7.5 for iPhone XS, XS Max, XR and iPad 7th generation
• macOS Tahoe 26.3, Sequoia 15.7.4, Sonoma 14.8.4
• tvOS 26.3 for Apple TV HD and Apple TV 4K
• watchOS 26.3 for Apple Watch Series 6 and later
• visionOS 26.3 for Apple Vision Pro
• Safari 26.3 for supported macOS versions

If your device qualifies, update it as soon as possible.

Why this update deserves attention

Security updates can feel routine. Many of us see the notification and decide to deal with it later. This time is different. Apple confirmed the flaw was actively exploited. That means attackers already know how to use it. Running older software gives them a window of opportunity. Updating closes that window.

How to update your iPhone or iPad

Updating takes only a few minutes.

• Go to Settings
• Tap General
• Tap Software Update
• If an update appears, tap Download and Install
• Turn on Automatic Updates so you do not miss future fixes

Keep your device connected to Wi-Fi and power during the process.

MALICIOUS MAC EXTENSIONS STEAL CRYPTO WALLETS AND PASSWORDS

Ways to stay safe

Installing this update is the most important step. Still, there are additional habits that strengthen your protection.

• Turn on automatic updates for every Apple device
• Restart devices regularly to clear temporary processes
• Avoid clicking unsolicited links or attachments, and use strong antivirus software. Get my picks for the best 2026 antivirus protection winners for your Windows, Mac, Android and iOS devices at Cyberguy.com.
• Remember, Apple threat notifications will never ask for passwords or verification codes
• Be cautious when viewing HTML-formatted emails in Apple Mail
• Consider enabling Lockdown Mode if you face a higher risk

Cybercriminals rely on hesitation. They count on us assuming we will get to the update later.

Kurt’s key takeaways

Apple moved fast to fix this vulnerability, and that is reassuring. Now it is up to us to do our part. I get it. Updates interrupt your day. They force a restart. They rarely feel urgent. But here is the thing. Installing updates is still the simplest and most effective way to protect your device from active threats. A few minutes now can prevent a serious security problem later.

What is your biggest reason for delaying updates, and has it ever cost you? Let us know by writing to us at Cyberguy.com.

Meta has struck a multiyear deal to expand its data centers with millions of Nvidia’s Grace and Vera CPUs and Blackwell and Rubin GPUs. While Meta has long been using Nvidia’s hardware for its AI products, this deal “represents the first large-scale Nvidia Grace-only deployment,” which Nvidia says will deliver “significant performance-per-watt improvements in [Meta’s] data centers.” The deal also includes plans to add Nvidia’s next-generation Vera CPUs to Meta’s data centers in 2027.

Meta is also working on its own in-house chips for running AI models, but according to the Financial Times, it has run into “technical challenges and rollout delays” with its chip strategy. Nvidia is also dealing with concerns about depreciation and chip-back loans used to finance AI buildouts, as well as the pressure of competition. CNBC notes that Nvidia’s stock dropped four percent after a November report about Meta considering using Google’s Tensor chips for AI, and late last year, AMD announced chip arrangements with both OpenAI and Oracle.

Nvidia and Meta did not disclose how much the deal cost, but this year’s AI spending from Meta, Microsoft, Google, and Amazon is estimated to cost more than the entire Apollo space program.

The whole country is watching the Nancy Guthrie case. When the suspected kidnapping happened, I was curious. How long would it take me to find her home address and cell phone number on a people search site?

About 30 seconds.

STOP FOREIGN-OWNED APPS FROM HARVESTING YOUR PERSONAL DATA

I then pasted her address into Zillow and saw photos of her home. I could match what I found to the video from a home tour done on the Today show. I could see the layout. The entry points. The windows. Where her furniture sat. Imagine if I was a criminal armed with that info.

Here’s the thing: I’m not some hacker. I used free websites anyone can access from their couch.

This is happening everywhere

In Scottsdale, Arizona, two teens dressed as delivery drivers forced their way into a couple’s home. They duct-taped and assaulted the homeowners, looking for $66 million in cryptocurrency. They got the victims’ home address from strangers on an encrypted app.

In Delray Beach, Florida, a retired couple had their sliding glass door shattered by thieves. The attackers had their home address from leaked personal data. That crew went on to hit victims in multiple states.

Riverside, California, police confirmed detectives routinely find Zillow and Redfin searches on phones seized from arrested burglary suspects. 

A former NYPD detective put it bluntly: today’s burglars can case your home from their chair with a cup of coffee and get better intel than they ever could sitting outside with binoculars.

HOW TECH IS BEING USED IN NANCY GUTHRIE DISAPPEARANCE INVESTIGATION

The numbers are scary

Zillow’s database covers over 160 million homes. Listing photos often stay online long after a home is sold. That means photos of your home, taken when you listed it three, five, even 10 years ago, could still be sitting there right now showing every room, every door, every window and exactly where your security cameras are mounted.

Google Street View covers 10 million miles of road worldwide. Criminals use it to check out vehicles parked in driveways, scope backyards and plan escape routes. In some areas, police say thieves are even using drones to peer into windows and check for dogs.

Anyone can type your name into a free people search site and get your home address in seconds. Then they plug it into Zillow and see your floor plan, entry points, window types and where the security cameras sit.

Unless you’re selling your home, take down your photos. Now.

Take it all down in 10 minutes

These steps can look a little different depending on your device, app version or browser. If it’s not exact, poke around. The option is there.

Zillow: Sign in at zillow.com. Click your profile icon > Your Home. Search your address, claim it, then go to Edit Facts and hide or delete the photos. Hit Save.

MAKE 2026 YOUR MOST PRIVATE YEAR YET BY REMOVING BROKER DATA

Redfin: Sign in at redfin.com. Go to Owner Dashboard. Select your home > Edit Photos > Hide listing photos > Save.

Realtor.com: Go to realtor.com/myhome. Claim your home, then select it under My Home > Remove Photos > Yes, Remove All Photos.

Google Street View: Open Google Maps on a computer. Search your address, drop into Street View, then click “Report a problem” (bottom right). Position the red box over your home. Under Request blurring, select “My home.” Submit. FYI, once it’s blurred, it’s permanent. Good.

Pro tip: Ask your old listing agent to pull photos from the MLS. Once they’re gone from MLS, the feeder sites eventually follow.

Also, while you’re at it, search yourself on people search sites like Spokeo, WhitePages and BeenVerified. Most let you opt out. It takes some time per site, but it cuts off the first step criminals use to find you. Better bet is to sign up for Incogni, a sponsor of my national radio show and podcasts.

If you’re not selling, there’s zero reason for the internet to have a virtual tour of your home. Take it down today.

I guess you could say Zillow gives everyone an open house. Problem is, you never sent the invitations.
